It's a stretch of road, that makes you want to throw yourself along it at high speed to cause as much scrape damage as possible.
Like, the compulsion to do so only increases the more you are on said stretch of road.
it just, became active one day and since then an increasing number of accidents have occurred.

Effect is persistent regardless of means of transport, be it foot, bike, car, plane, misc vehicle. if you have any control what so ever you will try and find a way to grind your body into road paste at high speed.

There are a couple sort of "lonely road" SCPs but I dont think they are like this or very similar to this, so in that regard you're okay. But, having said that, this is sort of a…"mind-affecting compulsion that makes you kill yourself" thing, and those tend to not do well without a good deal more to the story than what you've outlined above.

To what end is this being done? Just to cause death?

Why scraping/grinding?

Why this stretch of road?

Why all forms of transportation?

Consider holding off on drafting this until you can answer at least some of those above questions.
